The discovery, announced on Thursday by the Universities of Oxford and Birmingham, was made last summer when a worker digging up clay in a quarry in Oxfordshire noticed unusual bumps.

that finding led to a week-long excavation in June which unearthed five extensive trackways that form part of a dinosaur highway.

Four sets of tracks were made by herbivores called sauropods, which meawure up to 60 feet long.

The Centiosaurus comes from the Middle Jurrasic period, living 168 million years age in what is now Britain and probably France.

One track was made by the ferocious Megalosaurus, a carnivore with a distinctive triple claw print.
